Soil moisture is a crucial factor for the growth and development of plants. Measuring soil moisture can provide a basis for irrigation decisions, avoid the waste of water resources and soil salinization caused by excessive irrigation, and prevent the impact of insufficient irrigation on crop yields. Currently, common methods for measuring soil moisture include the oven-drying weighing method, the Time Domain Reflectometry (TDR) method, etc. The oven-drying weighing method involves taking a certain amount of soil, drying it, and then weighing it. The water content is calculated through the weight difference before and after drying. Although it has high accuracy, the operation is cumbersome. The TDR method determines the water content by using the propagation time of electromagnetic waves in the soil. It is easy to operate and the measurement is rapid.
Soil temperature also affects the growth of plant roots, microbial activities, and the conversion of nutrients in the soil. Accurately measuring soil temperature helps to understand the growth environment of plants and predict the growth cycle of crops. Measurement methods include the mercury thermometer method, the thermocouple method, etc. The mercury thermometer method directly inserts into the soil for measurement. It has a low cost, but it is easily damaged and has a limited measurement range. The thermocouple method measures by using the thermoelectric effect. It has high accuracy and a fast response, and is suitable for multi-point continuous monitoring.
The FT-WSYP1 Soil Temperature and Moisture Meter integrates the functions of measuring soil moisture and soil temperature. Based on sensors, it can quickly and accurately obtain data. This instrument has the characteristic of convenient operation, and the data can be directly read through the display screen. At the same time, it supports data storage and transmission. The measured data can be stored inside the instrument, and can also be transmitted to a computer wirelessly or via a cable, which is convenient for data management and analysis. It has good protection performance and is suitable for different field environments, providing an efficient and stable measurement solution for soil parameters in fields such as agricultural scientific research and farmland management.
